摘要
对广东省西江林业局6年生的9个桉树优良无性系进行生长调查,结果表明:单株材积、胸径、树高等生长性状在无性系间的差异均达到极显著水平。共有6个无性系单株材积生长优于对照,达到显著差异水平。表现最好的无性系为广林4号,其次为DH3327,其平均单株材积分别为对照的325.4%,323.6%,是总体均值的153.0%,152.2%。运用标准差法进行优良无性系选择,广林4号和DH3327两个无性系入选,入选率为22.2%。
9 super Eucalypt clones collected by West River forestry bureau was planted in 1999. 6 years later, the growth performance include single timber volume, D. B. H and hight was investigated. The result showed that there were extremely obvious differents between the clones growth performance. 6 clones volume were obviously higher than the contrast. Using the standard method, 2 clones of Guanglin 4 and DH3327 being selected for its best volume which was 325.4% and 323.6% compared with the contrast, and 153.0%, 152.0% compared with the average.
